       6. The oil supply carrier assembly of  claim 5  wherein the second oil supply passage is fluidly connected to the at least one mounting bore. 
     
     
       7. The oil supply carrier assembly of  claim 6  wherein the second oil passage is collectively defined by a first oil pathway, a second oil pathway and a third oil pathway, wherein the second oil supply passage delivers oil to a first engine brake rocker arm and a second engine brake rocker arm. 
     
     
       8. The oil supply carrier assembly of  claim 7  wherein the at least one mounting bore comprises a first and third mounting bore that receive an engine brake rocker arm thereat and a second and fourth mounting bore that receive a non-engine brake rocker arm thereat. 
     
     
       9. The oil supply carrier assembly of  claim 8  wherein the first, second, third and fourth mounting bores are alternately arranged on the oil supply carrier wherein the second oil supply passage delivers oil to the first and second engine brake rocker arms while bypassing the second mounting bore. 
     
     
       10. The oil supply carrier assembly of  claim 5  wherein the third oil supply passages are defined by a first lubrication line, wherein the first lubrication line accepts oil at the first inlet port and communicates oil to outlets defined at both of a first and a second mounting bore of the at least one mounting bores. 
     
     
       11. The oil supply carrier assembly of  claim 10  wherein the third oil supply passages are further defined by a second lubrication line, wherein the second lubrication line accepts oil at the second inlet port and communicates oil to outlets defined at both of a third and a fourth mounting bore of the at least one mounting bores. 
     
     
       12. An oil supply carrier assembly configured to be mounted to a valve train carrier having a plurality of rocker arms including first and second engine brake rocker arms and first and second non-engine brake rocker arms, the oil supply carrier assembly comprising:
 an oil supply carrier housing having a first oil inlet port, a second oil inlet port, a first mounting bore that mounts the first engine brake rocker arm, a second mounting bore that mounts the first non-engine brake rocker arm, a third mounting bore that mounts the second engine brake rocker arm, and a fourth mounting bore that mounts the second non-engine brake rocker arm, the oil supply carrier housing supporting an oil control valve and further having:
 a first oil supply passage configured therein to deliver oil from the first oil inlet port on the valve train carrier to the oil control valve; 
 a second oil supply passage configured therein to deliver oil from the valve train carrier to the first and second engine brake rocker arms; and
